How to remove an invisible space between div tags

Tags: html,css

Problem :

I have built several web sites and now i am having newbie problem that is driving me nuts...

Here's my code:

<div id="page">
<div id="page_wrapper">

    <div id="header">
        <h1>Heading 1</h1>
    <div class="clear_both" />&nbsp;</div>
    </div><!-- end #header --> 

    <div id="main_menu">
        <p>Here goes the main menu</p>
    <div class="clear_both" />&nbsp;</div>
    </div><!-- end #main_menu --> 

    <div id="left">
    </div><!-- end #left --> 

And here's my CSS

First i have a CSS Reset template from here:

and then on another file:

body, html {
    font: 10pt Verdana,Arial,sans-serif;
    background: #fff;
    margin: 0;
    padding: 0;
    text-align: left;
    color: #333;
div {
    line-height: 1.4em;
#page {

#page_wrapper {

#main_menu {

#left {

div.clear_both {
    margin: 0;
    padding: 0;
    font-size: 0;
    height: 0;
    line-height: 0;
    clear: both;

And on the link below there is an image screenshot on which you can see the output... (i am working on a local server)

There is an unexplainable space between the div tags I CANT REMOVE IT and it is driving me nuts... please can someone tell me how to remove it? I have tryed adding a negative top margin but from my previous experience it is not a solution... usualy seting the margin and the padding to 0 was enough... somehow now it is diferent :S

Unexplainable DIV space

Solution :

I've finaly found the problem thanks to all of You but especialy thanks to Notepad++

The problem was caused by the invisible blank spaces (from the SPACE key). I don't know why, but according to my knowlege this is the first time multiple space strokes to be detected by the browser.. I guess the newer browsers now are registerng more then one blank space after another.

I just opened the html scripts with Notepad++ and set from View->Show Simbol->Show All Characters. Then i've deleted all of the unneccessery empty spaces and that solved my problem.
